Recent studies in social endocrinology have explored the effects of social relationships on female reproductive steroid hormones-estradiol and progesterone-investigating whether they are suppressed in partnered and parous women. Results have been mixed for these hormones although evidence is more consistent that partnered women and women with young children have lower levels of testosterone. These studies were sequential to earlier research on men, based on Wingfield's Challenge Hypothesis, which showed that men in committed relationships, or with young children, have lower levels of testosterone than unpartnered men or men with older or no children.

Introduction: While many aspects of female ovarian function respond to environmental stressors, estradiol (E2) appears less sensitive to stressors than progesterone, except under extreme ecological conditions. However, earlier studies relied on saliva samples, considered less sensitive than blood. Here, we investigated E2 variation among 177 Bangladeshi and UK white women, aged 35-59, using single serum samples.

Background And Objectives: Low levels of vitamin D among dark-skinned migrants to northern latitudes and increased risks for associated pathologies illustrate an evolutionary mismatch between an environment of high ultraviolet (UV) radiation to which such migrants are adapted and the low UV environment to which they migrate. Recently, low levels of vitamin D have also been associated with higher risks for contracting COVID-19. South Asians in the UK have higher risk for low vitamin D levels.

Aims: The aim of this study was to assess patient satisfaction with a clinical psychology service, integrated within an inter-disciplinary orthognathic planning clinic.

Method: A self-report, custom-designed questionnaire was sent to patients who had completed orthognathic treatment within the last three years. Of the 60 patients approached, 49 responded.

Objectives: To evaluate the effectiveness of Buena Salud, a multidisciplinary enhanced primary care program for Medicaid Managed Care patients at a community health center serving a low-income Hispanic community.

Study Design: Controlled before-and-after observational study.

Methods: We extracted data from the electronic health record for patients aged 18 to 64 years with a) type 2 diabetes (T2D) enrolled in the Buena Salud program between August 2011 and January 2012 and b) randomly selected control patients with T2D who had been seen at the study health center during the same time frame.

Background: Pediatric practices' scores on healthcare quality measures are increasingly available to the public. However, patients from low-income and racial/ethnic minority populations rarely use these data. We sought to understand potential barriers to using quality data by assessing what factors mattered to women when choosing a pediatric practice.

Background: Consumers rarely use publicly reported health care quality data. Despite known barriers to use, few studies have explored the effectiveness of strategies to overcome barriers in vulnerable populations.

Methods: This randomized controlled trial tested the impact of a patient navigator intervention to increase consumer use of publicly reported quality data.

Objectives: A lifespan approach was used to evaluate age at menopause, and determinants of surgical and natural menopause, in the multi-ethnic community of Hilo, Hawaii.

Study Design: Participants aged 40-60 years (n=898) were drawn from a larger, randomly generated sample recruited by postal questionnaires. Median age at natural menopause was computed by probit analysis.

Objectives: To assess how different variables experienced across the life course, but particularly during early life, might affect age at menopause among 174 Bangladeshi migrants to London by comparing them to 157 nonmigrant sedentees and 154 women of European descent in London.

Methods: Participants were aged 35-59 years, with no exogenous hormone use in the past three months, not pregnant or lactating, with no history of hysterectomy or oophorectomy. Face-to-face interviews and anthropometric measures were carried out.

How many times have procedures in your operating rooms been delayed because the instruments needed were still in the sterilizer? As Perioperative nurses you are likely to be quite familiar with the constant pressure to ensure that scarce instrumentation is available when needed. In 2003, a Canadian company developed a unique sterilization process employing ozone as the sterilizing agent. This technology is a safe, rapid and economical alternative to other low temperature sterilization modalities and may relieve some of the pressure experienced when instruments in short supply are in high demand.
